About the role

Resolve inbound support tickets across question types — general knowledge, bug triage, and data requests — via omni-channel support, communicating clearly and professionally in async channels with a consistent, helpful tone. Triage and escalate issues to Customer Success or Engineering with enough context that handoff is seamless, and flag gaps in playbooks and escalation protocols when you find them.

What they're looking for

  • 6 months to 3 years in a customer-facing or technical support role — support, success, support engineering, or similar — ideally with exposure to building tools or automations
  • Customer-first orientation — you care about the experience on the other end of every response, not just whether the ticket is technically resolved
  • Technically capable and systems-oriented — comfortable scripting, building integrations, and working with APIs, data pipelines, or AI/LLM-powered workflows to remove manual work
  • Strong written communicator in async channels — crisp, clear, and professional
  • Fast learner who can absorb product complexity quickly, Rillet ships fast and support needs to keep pace
  • Strong triage instinct — you can quickly assess whether an issue needs investigation, escalation, or just a clear answer, and move it to the right place without losing the thread
